Has anyone done tire business with an online company named "World of Tires". They claim to have installers nation wide and their prices include installation and balancing.
When it comes to tires on any kind of RV, I think it's best to get them from a large national chain. One that you can find in almost any town so when you have a problem, it's easy to get addressed.
I've not heard of them but thousands of independent tire dealers getting a call from them with payment for installing the tires they ship them on your vehicle would get their interest. Not an unusual arrangement at all. They're actually doing the legwork for you because there are many tire shops that can't balance a large RV tire...they try to sell you beads instead.
